To achieve this goal some blasting were done, changing the conditions of the blasting and the powder factor for the 20 SR. To analyze the fragmentation base on the analysis of the images of the rock blasted, a commercial software was used. The results from this analysis were compared with the results from the theoretical model for fragmentation created by Kuz – Ram. After all, it was showed that the 20 SR explosive is able to pull out the coal for different coal rock compositions. As the result of this project we can conclude that the 20 SR seems to be able to pull out the coal in normal blasting conditions, using the powder factor as a proportion of the “ballistic mortar” between the two explosives.E.T.S.I.
